Problems solved by technology

[0004] In the process of uploading data from the above user equipment, the inventors found that there are at least the following problems in the prior art: the uplink data of multiple user equipment may be sent at the same time during the uplink transmission of the user equipment on the supplementary network, resulting in collisions
For data with relatively high QoS (Quality of Service) requirements, multiple collisions and retransmissions increase the transmission delay of uplink data

Embodiment 1

[0051] An embodiment of the present invention provides a data offload transmission method, the method is used on the side of the base station, such as figure 1 As shown, the method includes the following steps:

[0052] 101. The base station obtains a transmission performance parameter of the user equipment on the supplementary network.

[0053] During data offload transmission, in order to avoid multiple collisions and retransmissions when the user equipment transmits data on the supplementary network, the base station can schedule the transmission of the user equipment on the supplementary network. Supplements the transmission performance parameters on the network. The transmission performance parameters include: at least one parameter among data transmission delay and signal quality parameters. Wherein, the signal quality parameter includes RSSI (Received Signal Strength Indication, received signal strength indication), of course, the signal quality parameter can also be ...

Embodiment 2

[0102] An embodiment of the present invention provides a data offload transmission method, the method is executed by a user equipment, such as Figure 8 As shown, the method includes:

[0103] 801. The user equipment receives a transmission restriction event sent by a base station.

[0104] The transmission restriction event includes: event 1, when the data transmission delay is higher than threshold 1, the user equipment stops data transmission on the supplementary network; event 2, when the data transmission delay is higher than threshold 2, the user equipment segments the data The length is reduced to threshold 3; event 3, when the data transmission delay is higher than threshold 4, the user equipment only transmits the data on RB (Radio Bear, unlimited bearer) or logical channel on the supplementary network; event 4, when the signal strength is low At threshold 5, the user equipment stops data transmission on the supplementary network; in event 5, when the signal strength...

Abstract

Embodiments of the present invention relate to the field of communications, and provide a data distribution transmission method, apparatus and system, to avoid multiple collisions and retransmission and reduce the transmission delay of uplink data. The method comprises: a base station obtaining a transmission performance parameter of a user equipment on a supplement network, configuring a user transmission limitation according to the transmission performance parameter, and sending the user transmission limitation to the user equipment, so that the user equipment performs data transmission on the supplement network according to the user transmission limitation. The method provided by the embodiments of the present invention is applied to data distribution transmission.

Description

technical field [0001] The present invention relates to the field of communications, and in particular to a data split transmission method, device and system. Background technique [0002] With the increasing abundance of mobile Internet services, the amount of data in wireless communication networks has increased sharply. In order to alleviate network congestion, network operators have adopted data distribution methods to distribute part of the business data in the communication network to other available channels such as WiFi (Wireless Fidelity , Wireless Fidelity) network, femtocell network and iMB (integrated Mobile, integrated mobile broadcast) network and other supplementary networks. The specific method of data distribution between the user equipment and the communication network is: part of the data transmitted between the user equipment and the base station in the communication network is directly transmitted through the air interface of the network, and the other p...
